How do you use AA batteries instead of 9V?

Connect six of the AA or AAA batteries in series end to end, positive to negative and you’ll have nine volts. Each of those cells is 1.5V so if you connect 6 of them in series the voltage will be additive, in this case 9. AA batteries will give you 9V for a longer time- more capacity.

Are there AAA batteries in a 9 volt battery?

It’s not. All 9V’s are made from six 1.5V cells, but “AAA” has a specific meaning. No 9V uses them, they’re too big to fit in the case. The cylindrical cells that look like AAA’s are smaller – they’re not AAA’s, and they have a much lower capacity.

Is a 9 volt battery 6 AAA?

Each individual cell is 1.5 volts, so 6 x 1.5 = 9.0 volts. For a size comparison, a standard triple-A (AAA) cell is shown next to one of the AAAA cells. So, each AAAA cell is rated at 2.1 amps with an energy capacity of 550 mAh (milliamp-hours).

Can you use other batteries instead of 9V?

Many devices use alkaline batteries for electrical power. Some devices use standard 9V batteries. However, other devices require a 9V DC power source, but use a combination of AA, C, or D cells to add up to 9V.

Do 9V batteries last longer than AA?

The AAs or AAA’s have more Ah capacity than a 9V, so will last longer. The 9V also wastes more energy when dropped to 5V.

What devices use 9V batteries?

A nine-volt battery, either disposable or rechargeable, is usually used in smoke alarms, smoke detectors, walkie-talkies, transistor radios, test and instrumentation devices, medical batteries, LCD displays, and other small portable appliances.

What is equivalent to a 9 volt battery?

9V Battery Equivalents Cross Reference: 6LR61, 6AM6, Duracell MN1604, Rayovac A1604, Energier 522, Varta 4922, MX2400, 1604A, Radio Battery, Smoke Alarm, 9V Block, Krona, PP3.

Where 9V batteries are used?

smoke alarms
A nine-volt battery, either disposable or rechargeable, is usually used in smoke alarms, smoke detectors, walkie-talkies, transistor radios, test and instrumentation devices, medical batteries, LCD displays, and other small portable appliances.

What’s the point of 9V batteries?

What is the voltage of AA/AAA rechargeable batteries?

AA/AAA Alkaline batteries have a voltage of 1.5V AA/AAA NiMH or NiCd rechargeable batteries have a voltage of 1.25V

How much energy is in a 9v battery?

How much energy does a single energizer AA battery use?

A single Energizer AA, or E91, is rated for just under 3000 mAh at 25 mA drain. For this calculation, I picked 25mA because that is the nominal current draw for a 9 V. As a conservative value, let’s use 2750 mAh. Using the same energy formula before, we can calculate the amount of energy in a single 1.5 V AA battery.

How long do AA batteries last?

The Energizer AA batteries I just bought advertise 10 year life (if you don’t use them of course). So I assume that the competition would be offering similar life guarantees. If they are standard non-alkali – simple carbon batteries – if stored in the freezer their life can be years.
